Unit Assessment: The Water Cycle

Gravity plays a major role in the global movement of water in which of the following processes?

• Water vapor rising into the atmosphere

• Water flowing in rivers and streams

• The shifting of ocean currents as they strike land

• The expansion of water as it turns into ice

How are the processes of evaporation and condensation similar? Both evaporation and condensation–

• occur when water is heated by energy from the sun.

• are observed only in areas that have high winds.

• occur when water is moved between the ocean and the land.

• involve a change of the state of matter of water.

Which of the following would be a correct labeling of one of the arrows in the concept map?

• W = Precipitation

• X = Condensation

• Y = Transpiration and respiration

• Z = Evaporation

When developing a model of the cycling of water between the land, ocean, and atmosphere, one must include the forces that propel the water. For the model, these forces would be which of the following?

• Rivers, streams, and tributaries

• The polar ice caps and oceans

• Plants, animals, and human activity

• The sun’s radiation and gravity

Which of the following processes contributes most to the movement of water from land to the atmosphere?

• Evaporation

• Precipitation

• Condensation

• Crystallization

Why does most evaporation in the water cycle happen from Earth’s oceans?

In the diagram of the water cycle, describe which parts are driven by the force of gravity.
